I generated board files (Gerber x2s) for a design and the CM is saying the board files show multiple layers have the same physical location -and- that there are numerous instances of less than 3 mil space/trace. There are -no- such spacings space/trace and the stack looks fine. Someone explain to me what is going on, this is pretty strange. I need to get these files to the Contract Manufacturer asap.
Hello Jeffrey,
I am sorry to hear about this issue. Possible that those might be tiny stubs that were inadvertently placed during routing. To better examine the PCB, change the View to Draft mode. To do so, press L on the key board to access the View configurations dialog then go to the Show/Hide tab and change all to Draft. This will change the display of all objects to draft instead of full to better examine if you have any stubs or net antenna. You can also run the Net antenna design rule in the Design Rules window, under the Manufacturing category, there should be one by default already , make sure that it is enabled. You can adjust the net antenna length.

Pull the Rules &Violations panel from the View menu, select the Net antenna, right click and choose Run DRC Rule Class Net Antenna.
The violations section with the panel will display will the violations. If you click on the violation it will highlighted it and zoom in depending on your setting of the panel. (please see screen shots attached).
Hope this helps.
